Target-directed dynamic combinatorial chemistry is an important tool in drug discovery, but faces challenges in analyzing complex mixtures. In this study, we propose a simple alternative called in situ inhibitor synthesis and screening (ISISS), which combines high-throughput bioorthogonal synthesis with screening for target binding using fluorescence. We demonstrate the effectiveness of the ISISS method in discovering a potent acylhydrazone-based inhibitor of human prolyl hydroxylase 2 (PHD2), a target for anemia treatment, with comparable in vivo potency to an approved medicine.
Target-directed dynamic combinatorial chemistry has emerged as a useful tool for hit identification, but has not been widely used, in part due to challenges associated with analyses involving complex mixtures. We describe an operationally simple alternative: in situ inhibitor synthesis and screening (ISISS), which links high-throughput bioorthogonal synthesis with screening for target binding by fluorescence. We exemplify the ISISS method by showing how coupling screening for target binding by fluorescence polarization with the reaction of acyl-hydrazides and aldehydes led to the efficient discovery of a potent and novel acylhydrazone-based inhibitor of human prolyl hydroxylase 2 (PHD2), a target for anemia treatment, with equivalent in vivo potency to an approved medicine.
